Ok, i recently put an edelbrock 4 barrel intake, 1406 600cfm carb wth electric choke, and a new edelbrock fuel pump on my 1956 belvedere wth a basically stock 361 motor. I ordered everthing brand new from summit. i routed the fuel line got everything hooked up, it ran for a minute then died. It will not start and you can smell gas. I pulled the plugs and it flooded the motor pretty good. I keeps doing this. I checked the float level and the floats to see if they were cracked and letting gas in but they look fine. It pretty much is flooding the motor out after a couple cranks....I'm lost for ideas, anyone been through this before? fixes? thank you for any help you can provide.

Eddies cant take excessive pressure(what's your pumps' psi?) or debris in the gas getting by the filter. Float level is a 7/16" drill bit under the float at the outer end(gasket in place)

My initial thought is too much fuel pressure. IIRC, 5.5psi is what they recommend as a MAX pressure.

the reason i got the edelbrock fuel pump was it was designed to go with the carb at 6 psi i thought?

Can you R&R your stock pump back on & in 10 minutes time you'll know if its a psi problem

Can you look down the carb and see if its pissing gas in to the intake?

Does the engine have vacuum?

it is getting gas into the intake, it is getting vacuum. should i get some step down the metering rods? should i run hotter plugs? I'm running autolite 85 plugs in it now, they are a couple weeks old but have gotten very wet from fouling out.

I can't get it to run so i can't check the fuel squirting in when idling...it just floods out after cranking not very long. I will try cranking it and see if fuel drips in..if it does what does that mean? I read the manual before i installed the carb. thank you for the tips so far.

I found the 1406 to be two steps rich when new on my mild 360, so going two steps leaner with new rods and jets helped a lot.

That said, don't go changing anything on your engine until you finish the troubleshooting.

Is the choke working properly? 12v power to the red wire (not from the coil + terminal )?

I'd suggest you install a fuel pressure gauge and deal with the fuel supply first.

Mechanical fuel pump?
I don't know if Eddy has an electric.

Sounds like it's bleeding fuel somewhere. Leave the key off and jump the starter solenoid while looking down the carb. If it's dumping fuel you'll see it.

yes it is a mechanical fuel pump that is rated at 6 psi. I will try some of those tricks tommorrow and see how it goes...thank you for the advice!

Could be a defective carb. fill carb then shut off fuel pump and see if and how long it runs. nice to have a switch you can switch on momentarily to keep it running if flooding was the problem from to high a float.

To much fuel pressure. Put a stock pump back on it.

I went through this myself, it was a bad needle/seat. The float level was fine, the seat was just was not sealing all the way. You can test it yourself easily, just flip the carb over and try to blow into the fuel inlet. If you can blow into it, it isn't sealing. Yeah sure, it could be fuel preessure, but he claims it is a stock pump. I would also check the float level again, after that, things on the floats get bent easily, and the measurements aren't correct anymore.

Sounds like a bad needle / seat or improperly adjusted float. If it flooded that badly check your oil. Chances are it is contaminated with fuel. Might want to change to oil before you fire it up to save those bearings.

If you pull the top off the carb, check the floats for pinholes. It's really rare to see it on a new carb but if they fill with fuel they will sink and flood the engine.

Hey there again from Florida......float level or bad needle and seat..'56 w/ 440..I have a factory reman 800 cfm from Eddy and I'm not using it because while I sent it back for them to fix it I got my Holly working great..

Well I pulled apart the carb, the floats are set right at 7/16 as they recommend. I also tried blowing into the inlet and I COULD NOT blow in to it. So it is sealing right. My conclusion is it has to be too high of fuel pressure, I am going to get a fuel pressure regulator tommorrow and guage and see what happens. I will let you guys know the update tommorrow when I try it out. Thank you for all of the replies and ideas!
